The VAC2 module has updated. CampStaff was online during this update and did notice this Steam-wide update. I can confirm that there is a change in the CRC. Credit: Suxx, Patrick, ORGANNER
What this means for you.
* The client VAC module has possibly been updated to include the most recent cheats
* Dont use any hacks, no matter how long ago they were released
* When the client VAC module updates, it means there have been detections added outside of the CRC checksums that are added usually to the server side checks.
